This is a fairly new Butterick pattern by Palmer and Pletsch. I choose it because it seemed very much like what is in the shops right now, slightly oversized, not too fitted.
I was also intrigued by the ‘Palmer Pletsch’ Tissue Fitting Method shown on the pattern.
For a pattern of the ‘Big Four’ the instructions were very detailed, especially the first couple of pages describing the fitting process.
In the end I didn’t actually follow the tissue fitting guide. I felt it was fairly impossible to do by myself and frankly I was impatient to crack on.
However I did take the advice to size down, if in between sizes.
My measurements are 35” bust, 31” waist, 37” hip.
I took a big gamble and went for the size 12 ( bust 34”)!
I did check the pieces against other older ready to wear blazers, both of which were now a little small and it seemed I still had plenty of seam allowance to play with.
I first took 3 inches off the arm length and 1.5 inches off the jacket length at the shortening/lengthening lines on the pattern.
I made other adjustments as I went along all of which are in my blog post here. https://lovelucie.org/2022/08/30/butterick-6862-blazer/
